Compared to most QBs I wouldn't even say Dak is aggressive, even the current version of him. Most of his INTs seem to come on simple bad reads, option routes where QB/WR just were not on the same page, or when he does get aggressive is when playing from behind like in the SF game. I think you were spot on in your previous post about Dak loving the blitz, hating the deep shell coverages. You give Dak an open part of the field and he can tear up a defense if they are not well disguised. I think this is where some of the contradicting thoughts about Dak being bad against zone coverage yet his numbers against zone come from. I don't have a source that shows that specific of charting, but I would assume Dak's numbers are significantly boosted by zone blitz's whereas a straight cover 4 probably show a lot of check down throws.
Where Dak is such a good player, one of the best in the league is deciding when to be aggressive. His turnover splits last year were very interesting to look at. Near the top of the league in short yardage INTs with 6, but just 1 turnover on deep passes all last year. I don't think Dak throws a great deep ball compared to other QBs, but the guy is extremely smart selecting when to take his shots. On deep balls last year Mahomes had 6 INTs, Allen had 9, Tua 7, Hurts 8. Dak was 2nd fewest in the league in deep ball INTs yet was 4th in the league in yards on deep passes too. The only player that was really better was Stroud who led the league in yards on deep balls, but didnt have any INTs, which both of those stats are crazy for a rookie QB.
